Answer:
Answer D (2206.5 ft^2) is closest to the calculated answer 2206.85 ft^2.
Step-by-step explanation:
We can break up this figure into a 30 ft by 50 ft rectangle and a circle of diameter 30 ft.
The area of the rectangular part is A1 = (30 ft)(50 ft) = 1500 ft^2.
The area of the circular part is A2 = π(15 ft)^2 = 706.9 ft^2
Thus, the total area is approx A1 + A2, or 2206.86 ft^2 (Answer D)
Answer:
a₄ = 1.25
Step-by-step explanation:
Given that,
First term of GP, a₁ = 10
The common ration of GP, r = 0.5
The nth term of the GP is given by :

So, the fourth term of the GP is 1.25.
All angles should add to 180, so 180-120 gives you 60, divided by 2 gives you a=30
Answer:
Part A) The polynomial has three terms
Part B) The terms are 
Part C) Is a 2nd degree polynomial
Part D) The name of the polynomial is a 2nd degree trinomial
Step-by-step explanation:
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
we have

The polynomial has three terms
The terms are

therefore
The polynomial is a trinomial
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
The term is 
The highest exponent is the 2 so this is a 2nd degree polynomial
therefore
The name of the polynomial is a 2nd degree trinomial
